LiberatorMAX Fire Wireless Headsets
CSB-900MAX / CSB-902MAX Radio Transmit
CSB-901MAX / CSB-905MAX Intercom-Only
USERS GUIDE
The LiberatorMAX Fire Headset is used in conjunction
with an MS-900MAX Base Unit and up to 6 additional
headsets to form a wireless intercom network that also
allows Radio Transmit headsets to operate a vehicle-
mounted mobile radio remotely.
Only the Radio Transmit headsets allow the user to
talk over the mobile radio, however all headsets on the
channel will hear received audio from the mobile radio
and from all other headsets on the channel.
The headsets and Base Unit can operate on any one
of 8 available channels – all headsets must be on the
same channel for network intercom operation.
A Portable Radio can be connected to the Headset
using a PRAC Cable. The Portable Radio will connect
exclusively to that headset – other headsets in the
group will not hear the received audio or be able to
transmit over the portable radio.
Instructions for using the LiberatorMAX headsets
with the MS-900MAX Radio Interface Base Unit can
be found in the MS-900MAX User Guide.

Questions and answers
the micro phone is not working on one of the headsets
The microphone on the Setcom LiberatorMAX CSB-900MAX headset may not be working due to the following reasons:
1. Headset Type: If the headset is an "Intercom-Only" model (CSB-901MAX / CSB-905MAX), it does not support radio transmission, meaning the microphone will not transmit over the mobile radio.
2. Channel Mismatch: The headset must be on the same channel as the MS-900MAX Base Unit and other headsets for network intercom operation.
3. Volume or Power Issues: Ensure the headset is powered on and the volume is set to an appropriate level.
4. Battery Charge: If the internal Lithium-Ion Polymer battery is low or depleted, the headset may not function properly.
5. Connection Issues: If using a Portable Radio, ensure it is properly connected using a PRAC Cable.
6. Environmental Interference: High temperatures or interference from other electronic devices could affect operation.
If issues persist, contacting Setcom customer service is recommended.
